I am an avian ecologist and study birds (particularly migratory songbirds) in upland and bottomland forest ecoystems and use observational and experimental field studies to address ecological questions and conservation issues. A primary focus of my research has been determining how habitat features and landscape composition affect nest predation and brood parasitism in breeding birds. My work in bottomland forests has also documented how hydrological restoration of forested wetlands affects breeding bird communities. Another major focus of my research has been studying brood-parasite/host interactions and their ecological and evolutionary ramifications. Finally, my long-term work on Prothonotary Warblers has addressed behavioral decision rules for site fidelity, natal philopatry and first-year survival, density dependent reproductive output, and the effects of a warming climate on the timing of breeding.
